Title: Clock crossover circuit
Inventor: YONEKURA TAKESHI
IPC: H04L7/00
Filed: 1987-02-19
Abstract: PURPOSE:To prevent unstable operation in case of clock crossover by using a 1st clock so as to detect the leading edge and the trailing edge of an input data, converting the result into an output synchronously with a 2nd clock and then using the converted output so as to reproduce a data synchronously with the 2nd clock. CONSTITUTION:The 1st clock is used so as to detect the leading edge and the trailing edge of the input data at a leading edge/trailing edge detection means 9. Then the two detection outputs are given to a leading edge clock crossover means 10 and a trailing edge clock crossover means 11 to convert them into the detection output synchronously with the 2nd clock. Then the detection output converted by the data reproduction means 12 is used to reproduce the data synchronously with the 2nd clock. Since no intermediate clock (CK) is used in this way, the possibility of unstable operation in case of clock crossover is improved.

Title: Electric cooker
Inventor: KATAKASU MAKOTO
IPC: A47J27/00
Filed: 1990-02-16
Abstract: PURPOSE:To obtain an electric cooker capable of detecting that a pot is placed at a proper position at which the pot is heated by a heater, by providing controller which outputs an output prohibition signal to the heater when a weighing device detects a weight less than that stored in a memory. CONSTITUTION:A weighting device 16 detects the weight W of a pot 11. Next, it is judged whether or not a switch 15a of an output device 15 is pressed. When it is pressed, a comparator 18 compares the weight W of the pot 11 detected by a weighing device 16 with a weight W1 which is stored in a memory 17 as the weight of the pot without ingredient in it. When W-W1<0, a heating controller 23 prevents a heater 12 from being energized and alarms the abnormality through an buzzer 22a and an LED 22c. Thus, when W-W1<0, it can be detected that the pot 11 is not placed at a proper position.
